Yes, the new firmware supports push-IMAP for any e-mail service that offers it. Not only does this work on the new iPhone, but also the older ones that have upgraded to the free 2.0 firmware offerred last week.

A couple of years ago (when I added 90% of the folders under my Inbox), webmail gave me an error when I attempted to just create a folder. I forget what led me to add the period, but doing that worked for all of the other folders. I was just surprised when I did the same thing I have done over 20 times before, and it didn't work.
Also, to answer another question... The full caps INBOX disappeared when I selected "Rebuild Folder Tree" from the DDLB on the folder edit page. "Work Stuff" is under the real Inbox now, but I still can't delete it.

I created a folder the way that we USED to have to do it by creating "Inbox.House Stuff". It created a separate inbox called "INBOX" with the House Stuff folder underneath it. I can browse to this folder, but I cannot delete it. The mail server tells me that it does not exists. What gives? Do I need some admin to remove it?

I currently have several disposable e-mail addresses at Sneakemail.com, which all forward into my Spamcop account. The page says that I should set up the mailhosts for each e-mail address I have. I registered the first address with no problems at all. When I registered the second address, it replaced the first one on the list of registered servers. Do I only need to register once per mailhost, or once per e-mail address (as the page says) ?
